Mission Overview

The Loss of Mars Polar Lander
The Polar Lander was the first attempt to land on Mars since the Mars Pathfinder mission of 1997. The cruise stage of the Polar Lander contained the two Deep Space 2 Microprobes, "Amundsen and Scott" (named for the South polar explorers of Earth) The lander and microprobes were in excellent health during launch and the nine-month transit to Mars. On December 3rd, 1999, about ten minutes before it was expected to land on the south polar region of Mars (the first time a mission had been sent to that region), the lander lost contact with Earth and it was never regained. JPL scientists are currently determining what happened to the lander; it's assumed that it crashed on the Martian surface. The microprobes also never were located and its assumed that they were destroyed on impact (one of them was projected to hit the side of a crater wall, a dangerous target because of the rocky terrain).

The Polar Lander's Mission
The Polar Lander was to carry out a 90 day primary mission followed by an extended mission lasting until a terminal hardware failure. The theme of the Polar Lander mission was "Volatiles and Climate History" on Mars. The lander would have searched for surface ice and possible signs of regular climate change. It would also have looked for physical evidence of the seasonal cycles of water, carbon dioxide, and dust on Mars. The search for water is important for understanding the climate of Mars, both now and in the past. Finding easily-accessible sources of water is a requirement for the future human exploration of Mars.

Deep Space 2: Mars Microprobes
The Deep Space 2 Microprobes were a technology demonstrator mission which would also have returned science about Mars. As the Polar Lander separated from its cruise stage in preparation of entering the Martian atmosphere and landing, the two probes presumably detached and impacted the ground. Unfortuantely they did not succeed in landing safely and sending back signals to the Mars Global Surveyor orbiting overhead. If they had been successful, the forebody of the probes would have extended 1 - 2 meters into the ground, and they would have drilled deeper into the ground to search for water.

23-Jun-2001 - Goldin waffles on blame for Mars failures (Florida Today)
Recent remarks to two different audiences have some wondering whether NASA Administrator Dan Goldin is dodging responsibility for two Mars failures without looking like he's dodging. In a speech earlier this month to a computing summit in Maryland, Goldin blamed the Mars failures on inadequate computer design tools and said his critics tend to "look for the guilty and punish the innocent." He adopted a different attitude, however, in a recent interview with Florida Today that touched on the 1999 loss of Mars Climate Observer and Mars Polar Lander on separate missions. "As an agency, we are willing to tell the world we made a mistake," Goldin said. "In the case of the Mars program, I believe that the people pressed too hard and they pressed too hard because I asked them to. Clearly we have to push it a little less aggressively."
1-Apr-2001 - U.S. Poised For Return to Mars (Aviation Week & Space Technology)
The $297-million Mars Odyssey mission, crucial for NASA's recovery from back-to-back Mars flight losses, is set for liftoff this week on a "do-or-die" mission to validate reforms in the wake of the failures. The Odyssey orbiter will search for "Martian oases" as targets for future U.S./European landers.
26-Mar-2001 - NASA And NIMA Continue Joint Review Of Mars Polar Lander Search Analysis (SpaceDaily)

22-Mar-2001 - Mars Polar Lander: NASA and NIMA at Odds Over Spy Agency Findings (Space.com)
NASA and the National Imagery and Mapping Agency (NIMA) are moving forward on joint studies to search for the lost Mars Polar Lander. The craft has been missing in action since it attempted to soft-land on the Red Planet on Dec. 3, 1999. The craft was believed to have crashed on Mars, busting itself up across the Martian terrain. But NIMA photo specialists have been poring over NASA-supplied photos snapped by the Mars Global Surveyor spacecraft, now in orbit about Mars. As a support agency of the Department of Defense, NIMA has long been associated with interpretation of high-resolution imagery snapped by Earth-circling military spy satellites.
21-Mar-2001 - Experts Find Hint of Mars Lander (AP)
Fifteen months after the Mars Polar Lander vanished, Defense Department imaging experts have spotted what may be a trace of the spacecraft on the surface of the Red Planet, a NASA official said. Experts at the National Imagery and Mapping Agency have spent months poring over high-resolution images of the region where the Polar Lander was to have set down.
19-Mar-2001 - Spy Agency May Have Located Mars Polar Lander (Space.com)
The Mars Polar Lander may have been found -- intact -- by a top-secret spy imagery agency. The National Imagery and Mapping Agency (NIMA) has been quietly scanning Mars pictures, looking for the Mars Polar Lander since early December 1999. According to a source close to the NIMA effort, photographic specialists at NIMA think they’ve spotted something. But NASA officials say it’s too early to tell.
11-Jun-2000 - NASA's claim of Mars Polar Lander 'achievement' draws criticism (Space Today)
NASA has sparked a new uproar over the failed $165 million Mars Polar Lander program because of a statement in a recently released report. This latest Mars-program controversy revolves around NASA's claim that a "target" was "achieved" because the spacecraft's robotic arm worked in testing on Earth, even though the arm and the entire Lander were lost after crashing into Mars in early December.
12-Apr-2000 - Panel chairman blames NASA management for Mars debacle (Houston Chronicle)
The House's chief overseer of NASA on Wednesday blamed mismanagement for two failed Mars missions but stopped short of calling for changes in the space agency's leadership. An independent review of the missions, which both failed in 1999, concluded last month that they failed because of inadequate testing, inexperienced staff, poor communication and insufficient funds. But Rep. James Sensenbrenner Jr., R-Wis., said those problems could have been avoided had management paid more attention to tests, employee training and budget management.
7-Apr-2000 - More Grief for NASA: Report Calls Deep Space 2 Microprobes Unfit (Space.com)

24-Mar-2000 - Congress, Mars & NASA (Alabama Live)
You don't get a Cadillac for the price of a Yugo. NASA is simply trying to make the most of the money it has. The facts as we know them: On Dec. 3, 1999, the Mars Polar Lander began descending to the surface of the red planet. And that was it. The probe was never heard from again. The spacecraft or its debris, if any exists, is lost in space or on the Martian surface, where recovery is not practical.

21-Mar-2000 - NASA knew Mars Polar Lander doomed (United Press International)
The disappearance of NASA's Mars Polar Lander last December was no surprise to space officials, UPI has learned. Prior to its arrival at Mars, a review board had already identified a fatal design flaw with the braking thrusters that doomed the mission, but NASA withheld this conclusion from the public. The probe was lost while attempting to land near the martian south pole on December 3.
21-Mar-2000 - NASA denies hiding Mars probe flaws (United Press International)
A NASA spokesman vigorously denied a United Press International article that NASA knew that the Mars Polar Orbiter was doomed prior to its December crash into Mars but kept the information from the public. Brian Welch, director of public affairs at NASA headquarters in Washington, said "we think the story is whacko in every particular."
14-Mar-2000 - Sloppy management blamed for Mars Climate Orbiter loss (Spaceflight Now)
An independent review board blames the loss of NASA's Mars Climate Orbiter last year on sloppy project management, a lack of agency oversight, poor communications and shortsighted engineering.

16-Feb-2000 - A Fatal Design's Single Bit (SpaceDaily)
However, during the actual Mars landing, the accidental setting of the ground-contact bit as soon as the legs unfolded would mean that later, when the lander cut itself loose from its chute and switched on its landing engines, it would instantly conclude that it had already landed and immediately switch the engines off again -- falling the remaining 1800 meters to the surface of Mars.
15-Feb-2000 - Polar Lander ‘Signals’ Probably a False Alarm (Space.com)
New analysis suggests that two faint signals thought to be from the Mars Polar Lander were likely terrestrial in origin, a Stanford University scientist said Tuesday. A 150-foot (46-meter) radio antenna at the Northern California university picked up the weak signals on December 18 and January 4, reviving hopes at the time that the errant Polar Lander remained alive. The $165 million spacecraft vanished December 3 after plunging into the martian atmosphere at the start of what was to have been a 90-day mission.
11-Feb-2000 - Seeking an SOS from Mars (Christian Science Monitor)
At first, Ivan Linscott just didn't think the odd signal amounted to much.
